JOURNAL-BOX.

Specification of Letters Patent.

Patented Dec. 17, 191 8.

Application filed February 8, 1918. Serial No. 215,590.

To all whom it may concern:

Be it known that I, JOHN TATUM, a citizen of the United States, residingat Baltimore, in the State of Maryland, have nvented certain new anduseful Improvements in JournalBoxes, of which the following is aspecification.

The object of my invention is to provlde a journal box with a bottomfioor of such construction that the sponging under the journal will beretained in place thereby 1nsuring proper applicatlon of 011 to thejournal.

A further object of my invention is to so construct the floor of thejournal box as to insure the oil with which the sponging is to be keptsaturated, being fed back by gravity to the sponging in case any of theOil, is thrown out or off from the sponging by movement of the journal,whereby the oil in the box is kept constantly in use to feed thesponging under the journal, so that the journal will always be keptsupplied with oil for lubrication; and with these and other objects inview my invention consists of the parts and combination of parts as willbe hereinafter set forth.

In the drawings:

Figure 1 is a vertical longitudinal sectional view of a journal boxembodying my invention.

Fig. 2 is a detail sectional view on the line 2-2 Fig. 1.

Figs. 3, 4, 5, and 6 are vertical longitudinal sectional views ofjournal boxes, the upper portion being broken away, showing otherembodiments of my invention.

Fig. 7 is a perspective view of the bottom wall of a journal box showingthe groove extending longitudinally of the floor and transverse of theundulations on the floor or bottom wall.

The reference numeral 8 designates a journal bearing, 9 the journal and10 the journal bearing wedge or key, all of M. C. B. construction.

According to M. C. B. practice the journal box is pac ed by firstplacing rolls 11 which are placed at the rear of the box to prevent oilfrom working out through the dust guard opening. The loosely formedsponging 12 is then firmly placed under the journal to avoid the samesettling away, packing it more lightly on each side of the ournal toavoid the wiping eifect produced when the waste is pressed too tightlybetween the journal and the side of the box. The height of the spongingmust not extend beyond the center line of the journal, nor beyond theinside of the journal collar. It is also the practice to place spongingbetween the end of the journal and the front wall of the box, but itmust have no thread connection with any of the sponging under or on theside of the journal, and must not extend more than one inch above thelower edge of the collar on the end of the journal. This sponging, whichdoes little or no lubricating, should be comparatively dry, as itsfunction is to prevent the sponging on the sides and under the journalfrom working forward out of the normal position for satisfactoryservice. In new equipment a journal box, according to its size requiresfrom about 7 to 20 pounds, while replacing requires from 6 to 16 pounds.As a result of my invention I am enabled to save approximately ten centsworth of packing in each of the eight journal boxes of a car or eightycents per car and as these packings are required about once a year itwill be seen that the saving is very material when the large number ofcars in use is considered.

In the simplest embodiment of my invention, shown in Fig. 1 I constructthe floor of the journal box on two different planes; the main floor 13,under the journal being in a lower plane than the plane of the floor 14beyond the outer end of the journal, there being a shoulder or stop 15at the juncture of the two levels which shoulder or stop, as will beseen from Fig. 1 keys the spongin in place under the journal and holdsit t ere in proper normal position, and prevents it from working towardthe front of the box. It frequently happens in the construction of M. C.B. box that the sponging works forward when the wheels jum overcrossings and frogs, but by reason of t e stop 15 in my constructionthis cannot happen.

By reason of my invention I dispense with the sponging placed in M. C.B. construction between the end of the journal and the front of the box.

In Fig. 3 I provide the lower floor 13" with a plurality of Stops 16faced toward the rear end of the box, the top of the stop being inclinedtoward the front of the box whereby oil is fed toward the front of thebox. While the vertical faces of the stops hold the sponging fromworking toward the front of the box. These stops are each provided witha transverse groove 17 which permits oil to feed from end to end- 01 thehon,

in Fig. l the lower floor 13 is provided with a series of stops 18 eachon a difierent and higher plane progressively disposed toward the frontoi the box.

ln Fig. 5 the lower door is provided with a plurality bf transversestops 19 all dieposed in substantially the same plane under the journal.'lhese stops 19 are each provided with transverse grooves similar to thegrooves 17 in Fig, '2'.

In Fig. 6 the stop 20 at the front of the box is undercut. it will benoted that the floor 14: is, in each instance, inclined downwardlytoward the rear of the box whereby oil thereon. is fed by gravity to thefloor and sponging under the journal, lhe usual dust guard 21 isemployed in my improved journal box. The lower inner wall 22 oi the dustguard groove is positioned a greater distance from the rear wall of thejournal box than is usual so that a space 23 is left between the lowerends of the dust guard and the wall 22, whereby the lower end of thedust guard groove is of greater width than the thickness of the dustguard. The object of this construction is to prevent oil from creepingalong the journal outside of the journal as is the ease with the presenttype of journal box. Any oil that may start to creep along the journalwill come in contact with the inner face of the dust guard 21 and therebeing no support for said oil at this point it will, by gravity, fallthrough the space 23 on to the bottom door of the journal box and passthrough the port 24 under the wall 22 into the sponging to be usedagain. By preventing the oil from creeping along the journal outside oithe box 1 not only save a considerable amount of oil but I eliminate thesplashing of the oil over the car wheel and associated parts.

It is of course obvious that the stops may be continued up the sidewalls of the journal. box to a proper height without departing from thespirit of my invention. lady in vention may be embodied in its entiretyin a journal box made of cast metal or of pressed metal.

What it claim is:

1. A journal box, a journal therein, said box having a shoulder or chockin the bot tom thereof in substantially the vertical plane of the frontend of the journal and terminating short of the periphery of thejournal.

2. A journal box having its lower dust guard wall oil-set toward thefront of the box whereby the groove for the dust guard is wider at thebottom oi the box than at the sides and the top of the box, said lowerwall having a port through it substantially at the floor of the box, sothat oil in moving toward the wheel will drop down into the open spacebetween the lower inner Wall of the dust guard and run back, through theport in the lower dust guard wall tothe sponging under the journal inthe box.

3. A journal box having a lower inside wall for the dust guard, a portat the bottom of said wall leading inside of the box so that the oilgetting into the lower dust guard groove will run back into the spongingin the box.
